Spendlo is a free Chrome extension developed by spendlo that aims to help users spend less on online shopping by assisting them in sticking to their budget. Unlike other tools that require users to actively check their budget, Spendlo provides the budget information right before making an online purchase. By presenting this information in-context, Spendlo helps users make better shopping decisions and save more money.

To get started with Spendlo, users can simply download the extension and sign in using their Facebook, Google, or Email accounts. They can then set a budget for the maximum amount they want to spend on online shopping each month. Spendlo will automatically recognize when users are on a shopping cart or checkout page and proactively display how much of their budget is remaining, enabling them to make more informed shopping choices.
